Multiple Choice
What is a common consequence when errors occur during DNA repair and incorrect or missing bases are left in the DNA sequence?
A
The cell becomes immune to further DNA damage
B
The DNA is immediately degraded by nucleases
C
The cell always repairs the DNA perfectly on the next attempt
D
Mutations are introduced into the genome
Verified step by step guidance1
Understand that DNA repair mechanisms are designed to correct errors that occur during DNA replication or due to damage.
Recognize that if errors during DNA repair are not corrected properly, incorrect or missing bases can remain in the DNA sequence.
Know that these uncorrected errors lead to changes in the DNA sequence, which are called mutations.
Realize that mutations can alter the genetic information, potentially affecting gene function and leading to various biological consequences.
Conclude that the common consequence of errors left in the DNA after repair is the introduction of mutations into the genome.
